Product details
Overview
TPS63001DRCT from Texas Instruments is a fixed-output 3.3 V, high-efficiency single-inductor buck-boost DC-DC converter designed for battery-powered systems. It operates from 1.8 V to 5.5 V input, delivers up to 1200 mA at 3.3 V in step-down mode (VIN = 3.6–5.5 V), supports automatic buck/boost transition, and features <50 μA quiescent current - enabling long runtime in portable medical devices and smart phones.
For engineers reviewing the TPS63001DRCT datasheet, TPS63001DRCT pinout, TPS63001DRCT application, or TPS63001DRCT equivalent, key selection criteria include its 3.3 V fixed output, 10-pin VSON (3 mm × 3 mm) package, 1.25–1.5 MHz switching frequency, power-save mode operation, and integrated 1.8-A synchronous switches - all critical for compact, battery-sensitive designs requiring stable rail generation across wide input voltage swings.
Technical Context
The TPS63001DRCT uses average current-mode control with input/output voltage feedforward for fast transient response and stable regulation during input voltage crossing the 3.3 V output threshold. Its 4-switch synchronous topology enables seamless transition between buck and boost modes while maintaining high efficiency near VIN ≈ VOUT.
It integrates dual ground domains (GND for control logic, PGND for power switches), undervoltage lockout (1.5–1.8 V on VINA), overtemperature protection (140 °C trip with 20 °C hysteresis), and soft-start with short-circuit limiting - ensuring robust startup and fault resilience in Li-ion and multi-cell alkaline/NiMH systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±1.5% - eliminates external feedback resistors and simplifies layout for dedicated 3.3 V rail generation. |
| Input Voltage Range | 1.8 V to 5.5 V - supports single-cell Li-ion (2.5–4.2 V), two-cell alkaline/NiMH (2.4–3.6 V), and three-cell configurations down to full discharge. |
| Max Output Current | 1200 mA at 3.3 V in step-down mode (VIN ≥ 3.6 V); up to 800 mA in boost mode (VIN > 2.4 V) - defines usable load capacity under real-world battery profiles. |
| Switching Frequency | 1.25–1.5 MHz typical - enables use of small 2.2 µH inductors and ceramic capacitors for space-constrained PCBs. |
| Quiescent Current | <50 µA - minimizes no-load battery drain, extending shelf life and standby time in always-on portable electronics. |
| Efficiency Peak | Up to 96% - achieved in mid-load range (e.g., 300–800 mA), directly reducing thermal stress and extending battery runtime. |
| Thermal Resistance | RθJA = 46.8 °C/W - requires minimal copper area for thermal relief in standard 2-layer boards with exposed pad soldered to PGND. |
Pinout & Package
TPS63001DRCT is housed in a thermally enhanced 10-pin VSON (DRC) package measuring 3.0 mm × 3.0 mm with an exposed thermal pad connected to PGND. The package supports reflow-compatible assembly and efficient heat dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (Pin 1) | Power output | Delivers regulated 3.3 V; must be decoupled with ≥10 µF ceramic capacitor close to pin and PGND. |
| L1 (Pin 4) | Inductor connection (high-side path) | Connects to one terminal of 2.2 µH inductor; carries high di/dt current - requires short, wide trace to minimize EMI. |
| L2 (Pin 2) | Inductor connection (low-side path) | Connects to second inductor terminal; forms buck-boost power loop with L1 and internal switches - routed adjacent to L1. |
| PGND (Pin 3) | Power ground | Return path for switch currents; must be tied to exposed thermal pad and kept separate from control GND until single-point star connection. |
| VIN (Pin 5) | Main power input | Supplies power stage; accepts 1.8–5.5 V; requires local 4.7 µF+ ceramic input capacitor between VIN and PGND. |
| VINA (Pin 8) | Control-stage supply | Provides bias for internal logic; shares same input source as VIN but has independent UVLO (1.5–1.8 V) - ensures reliable enable/disable sequencing. |
| EN (Pin 6) | Enable control | Active-high digital input; pulls device into shutdown (<1 µA ISHDN) when low - used for system-level power gating. |
| PS/SYNC (Pin 7) | Mode control / clock sync | Low = power-save mode enabled; high = forced PWM; external clock input synchronizes switching to avoid beat frequencies. |
| GND (Pin 9) | Control ground | Reference for FB, EN, PS/SYNC, and internal regulators - must connect to PGND at single point near IC to prevent ground bounce. |
| FB (Pin 10) | Feedback input | Internally tied to 3.3 V divider; for TPS63001DRCT, must be shorted to VOUT - no external resistor required. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic buck-boost mode transition | Seamlessly shifts topology without output disruption when VIN crosses 3.3 V - maintains uninterrupted 3.3 V supply during battery discharge. |
| Synchronous 4-switch architecture | Integrates two 100 mΩ high-side and two 100 mΩ low-side N-MOSFETs - eliminates external diodes and enables >90% efficiency across 10 mA–1 A loads. |
| Load disconnect during shutdown | Internal switches isolate VOUT from VIN when EN = low - prevents battery drain through downstream circuitry and enables true zero-IQ sleep states. |
| Programmable power-save mode | Reduces switching at light loads (IOUT < ~300 mA) via PS/SYNC pin - improves light-load efficiency by up to 15 percentage points vs forced-PWM mode. |
| Integrated thermal and overcurrent protection | Shuts down at 140 °C junction temperature with 20 °C hysteresis; limits peak switch current to 1600–2000 mA - protects against sustained overload and PCB overheating. |

FAQ
What is the output voltage configuration of the TPS63001DRCT?
The TPS63001DRCT features a factory-trimmed fixed 3.3 V output. Unlike adjustable variants (e.g., TPS63000), it does not require external feedback resistors - the FB pin must be directly connected to VOUT. This configuration reduces BOM count and layout complexity while guaranteeing ±1.5% output accuracy over temperature and load, making TPS63001DRCT ideal for dedicated 3.3 V rail applications.
Does the TPS63001DRCT support synchronization to an external clock?
Yes, the TPS63001DRCT supports external clock synchronization via the PS/SYNC pin. When driven with a TTL/CMOS-compatible clock signal (1.25–1.8 MHz range), the internal PLL locks to the external frequency - eliminating beat frequencies in multi-rail systems and enabling EMI reduction through spread-spectrum-like timing control. This capability is retained even when power-save mode is disabled.
How does the TPS63001DRCT handle input voltage transitions across the 3.3 V output level?
The TPS63001DRCT automatically transitions between buck and boost operating modes without interruption or output droop. As VIN drops below 3.3 V (e.g., from 3.6 V to 2.4 V during battery discharge), the controller reconfigures its 4-switch topology in real time - maintaining regulated 3.3 V output with <10 mV transient deviation. This seamless crossover is intrinsic to its average current-mode architecture and requires no external mode-control circuitry.
What thermal management provisions does the TPS63001DRCT include?
The TPS63001DRCT incorporates junction-temperature monitoring with overtemperature shutdown at 140 °C and 20 °C hysteresis. Its 3 mm × 3 mm VSON package features an exposed thermal pad tied to PGND, delivering RθJA = 46.8 °C/W. For continuous 1 A operation, TI recommends ≥200 mm² of 2-oz copper connected to the pad - enabling reliable operation up to 85 °C ambient without forced airflow.
Can the TPS63001DRCT be used with single-cell Li-ion batteries?
Yes, the TPS63001DRCT is explicitly designed for single-cell Li-ion and Li-polymer batteries. It starts up at VIN ≥ 1.9 V and operates continuously down to 1.8 V input - supporting full discharge from 4.2 V to ≤2.5 V while delivering up to 800 mA at 3.3 V in boost mode. Its undervoltage lockout (1.5–1.8 V on VINA) prevents deep discharge damage, making TPS63001DRCT a robust choice for consumer and medical Li-ion applications.
